First off, three very impressive females. I, of course, have no idea of your market/goals from the calves so I'll just make suggestions as if they were mine.
Impluse: Deep/soggy, beautiful utter I'd try to make a female. How about I Da Man, I80, Grizzly Bear, Maternal Perfection, Whizard from Griswold.
Firewater: Loved the picture of this Char, I'd for sure go for those smokey/char calves that are selling off the charts right now. Monopoly would be an obvious choice, Walks Alone, Unstoppable.
Money Man: I'd go for a market animal here too. Appears clean shouldered enough to try MAB, or BIM.
